Hi Rohan,

at first glance, it looks like you are assigning a CampaignId value that doesn't exist in the database.

That may happen if you are calling a Service Action after inserting the CampaignId. Since the Service Action will happen in a different transaction, that newly created Campaign still doesn't exist inside Service Action transaction.

Hello Rohan,

ORA-02291 is typically accompanied with the message, “integrity constraint <constraint name> violated – parent key not found”. This means that you attempted to execute a reference to a certain table using a primary key. However, in the process of doing so, the columns that you specified failed to match the primary key.
